Abstract: An incinerator (20) for disposing of boil-off gas on an LNG carrier comprises a combustion section (40) wherein the boil-off gas admitted at (42) is burned in the presence of combustion air admitted at (44), producing a flame (46) and combustion products (C). Dilution air (A) is delivered into the combustion section (40) and mixed with the combustion products (C) to produce a diluted mixture (M). The combustion section (40) has an inner wall (48) and an outer wall (50) together defining a first passage (52) through which the dilution air (A) is passed before being mixed with the combustion products (C), whereby the dilution air A cools the combustion section (40). The dilution air A in the first passage (52) also provides a thermally insulting layer limiting radial heat transmission from the combustion section (40). A proportion (AP) of the dilution air is mixed directly with the combustion products (C).

Abstract: An incinerator 20 for disposing of boil-off gas on an LNG carrier comprises a combustion chamber 42 wherein the boil-off gas admitted at 40 is burned in the presence of combustion air admitted at 44, producing a flame 46 and combustion products C. Dilution air A is delivered into the combustion chamber 42 and mixed with the combustion products C to produce a diluted mixture M. The combustion chamber 42 has an inner wall 48 and an outer wall 50 together defining a first passage 52 through which the dilution air A is passed before being mixed with the combustion products C, whereby the dilution air A cools the incinerator 20. The dilution air A in the first passage 52 also provides a thermally insulting layer limiting radial heat transmission from the combustion chamber 42. A flue 58 is configured and arranged so that the flame 46 is enclosed.

Abstract: A vacuum bag mounting assembly for housing a vacuum bag within a vacuum cleaner, where the vacuum cleaner includes a vacuum intake nozzle having an outlet end portion through which sucked in dirt is delivered to the vacuum bag housing assembly, including a vacuum bag storage compartment 1, a vacuum bag collar receiver disposed within the vacuum bag storage compartment that engages a collar of the vacuum bag, and a telescopic nozzle end attached to the outlet end portion of the vacuum intake nozzle, the telescopic nozzle end being moveable along the outlet end portion towards and away from the collar of the vacuum bag. The vacuum bag mounting assembly also includes a housing cover that covers the vacuum bag storage compartment, the housing cover including a nozzle engagement member that engages the telescopic nozzle.

The nozzle engagement member is attached to the telescopic nozzle end such that pivoting of the nozzle engagement member in a first direction results in movement of the telescopic nozzle end away from the collar of the vacuum bag and pivoting of the nozzle engagement member in a second direction results in movement of the telescopic nozzle end towards the collar of the vacuum bag.

Abstract: A vacuum bag housing assembly for housing a vacuum bag within a vacuum cleaner including a vacuum bag housing, a mounting plate that receives a collar of the vacuum bag, and a plurality of linking members. Each of the plurality of linking levers includes a first end that is pivotally attached to the mounting plate and a second end that is pivotally attached to a fixed portion of the vacuum bag housing. The plurality of linking levers allows the mounting plate to swing between a down and out position and an up and in position within the vacuum bag housing.

Abstract: A vacuum cleaner filter having an outer textile fabric material laminated to a non-woven composite material. The composite material comprises an inner and an outer cover layer of a spun-bonded, non-woven web material, sandwiching at least one intermediate melt-blown layer.

Abstract: A system for supplying hydrogen gas to a lighter-than-air (LTA) vehicle includes a manifold having multiple vessels. Each vessel has a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on each vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached, and the hydrogen gas is supplied to the LTA vehicle connected to the manifold.
